Sure thing, let's get straight to it. We start with 681 and we're going to multiply it by 7, which means adding 681 to itself 7 times.
Step 1: 0 + 681 = 681
Step 2: 681 + 681 = 1362
Step 3: 1362 + 681 = 2043
Step 4: 2043 + 681 = 2724
Step 5: 2724 + 681 = 3405
Step 6: 3405 + 681 = 4086
Step 7: 4086 + 681 = 4767

So, 681*7 = 4767
